FEEDING MECHANISM FOR MANGLES.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, DANIEL M. COOPER, of in the county of Monroe and State of New York, have invented certain new and useful Improvements in Feeding Mechanism for Mangles; and I do hereby declare the following to be a full, clear, and exact description of the same, reference beingr had to the accompanying drawings, forming a part of thisspeciiication, and to the referencenumerals marked thereon.

The present invention relates to feeding` mechanism for mangles for clothes and other wash goods of the type in which the goods are fed b v a plurality of belts or aprons to the intake of the lnangle, and an object of the invention is to provide a support for the belts in proximity to the intake, which will not warp or bend under the action of the heat Iand the moisture and at the same time will be light in construction and inexpensive to n'ianufacture.

Another object of the invention is to sup` port and drive the driving rollerl of the belts in sucha manner that a like tension will be applied to all of the belts so that an uneven feeding is prevented. In the drawings.: Figure l is a side view ot' a portion of a mangle with parts. of the driving mechanism broken away to further illustrate it; Fig. 2 is a vertical section,

transverse to the 'axis of the mangle drum; l

Fig. 3 .is a front view of the feed table and its support.; Figs. 4 and 5v are Sections on line a-a and b-b, respectively, of Fig. 3; and Fig. G is a side view of one ofthe frames that support the belt driving roller. I'Fig. 7 is a detail view taken on the line-7*-7" of Fig. 2 5 Fig. 8 is a detail View simila 1' to F ig. 5, taken on the line 8-8x of Fig. 3; Fig. 9 is a detail sectional view taken on the line 9* of Fig. 2; and Fig. 10 is a detail sectional view illustrating the adjustability of- Pivotally mounted as at 4, preferably onbrackets 5 attached to the side pieces of the main frame, is a frame which may embody with oppositelyarranged seats on their inner faces to receive cross pieces or bars 10 which are connected by a flexible sheet -11 serving as a support for the inner ends of the wet goods that are carried by the usual removable bar 12. It will be noted that the pivot of the swinging roll frame is located on the rear side of the center of gravity of the frame and theA parts supported thereby. This arrangement causes the roller S to have a tendency to swing forwardly or away from the mangle drum, and to place tension on the endless belts 13 which it drives.

The belts 13 extend to -the int-ake'of the mangle, in this instance between drum 9 and roller 3, and pass around a rod or wear piece 14 which is supported 'by brackets 1G from a cross piece 17, being secured to the end brackets by screws 16a. The cross piece may be formed from angle iron and be supported at its ends below the belts on brackets 18 that are secured to the inner faces of the main-frame side-pieces. The -brackets 16 also support a'feed table or board 19 which is preferably formed .from sheet metal in order that it will not warp and will at the same time be light in structure, the forward edge of the table being turned downwardly at 20 so that the belts will travel freely thereover and the goods will not be caught by the edge.

Projecting betweenvthe drum 2 and the intake roller 3 is a plurality of fingers 20av which lie between the belts and prevent the goods traveling with the latter beyond their inner ends. Some of these fingers extend from some of the brackets 16, while others project from the feed table 19 and have the rod 14 arranged loosely therein. The upper edgesV of the fingers lie in a plane with the upper edge of the feed table so that the goods pass freely from the belts to the lingers. To accomplish this result the rear ends of those fingers which project from the table are formed with depressions 2l to receive the table, and the table is also titled in like depressions Vin the brackets 16, the

brackets and the fingers having laterally delected franges 22 at the depressions to which the feed Vtable is secured by rivets Q8 or other suitable means.

The roller 8 has the driving mechanism connected directly thereto and for this pur; pose one end may carry about which passes an endless sprocket chain 25. This sprocket chain may bedriven from a sprocket wheel 26 on the main frame and pass about two idlers 27`and 28 on a bracket, the idler 28 being movably mounted in order to take up slack in the sprocket chain.

The driving of sprocket wheel 26 is in this instance effected from a drive shaft29 which carries a worm 30 meshing `with a worm wheel 31 on the main frame. Arranged on the shaft of wormwheel 31 is a -gear wheel V32 which meshes with a gear 33 in turn meshing with a pinion 33x1 that is arranged on the shaft of sprocket wheel 26." The shaft of gear wheel 33 also carries a gear wheel 34 on the inner side of the main frame to mesh with the large ear'35 which is secured to the drum 2, to t rive the latter.

As the driving mechanism is connectedto one end of the driving roller 8 there is a tendency topull,

In operation, the bar 12 with the goods thereon is placed on the swinging frame, the to support the -inner ends of the goods out of Contact with the floor or dirty parts of the machine. ,'IhemaChine being 1n operation, the goods are laced by hand onthe aprons or belts 13 and` are carried thereby to the fingers 20a which direct them into the mangle. I Owing to the arrangement ofthe feed roller 8 on a. self adjusting frame it is possible tomaintain the belts 13 under an e ual tension at all times. The feed board an its adjacent parts are of a strong yet light construction whlch may be subjected to a great deal of wear without. liability of warping.
